Patent JP-H11505311-A (JP)
IPC: F16H3/72
Filed: 1996-05-13
Abstract: The invention is related to a rotational speed converter comprising shafts (1, 2) with bevelled gears fixed thereon, separate bevelled gears (3, 4) which cooperate with said gears fixed onto said shafts and are mounted on a separate shaft (5), a planetary gear (6) connected to said separate shaft, and at least one braking gear (7) acting on said planetary gear. In speed converter, according to the invention, are fluid flow channels (9, 10) connected to the braking gear (7), whereby the fluid volume surrounding said channels is filled with a hydraulic fluid that is arranged to pass through the gaps formed between teeth of the braking gear (7) and the planetary gear (6) from the suction side to the pressure side, and that the converter additionally incorporates a control valve for adjusting the fluid flow from the pressure side (9) to the suction side (10), whereby the hydraulic system thus formed makes it possible to control the fluid pressure on the pressure side thus permitting braking of the braking gear and the rotational speed of the planetary gear in a desired ratio, whereby a stepless conversion ratio from zero to 1:1 between the speeds of the input shaft (1) and output shaft (2) is attained.

Patent JP-2001508975-A (JP)
IPC: H04W16/12
Filed: 1998-02-13
Abstract: When a dynamic channel allocation method based on monitoring of signal levels is used for channel allocation, the results of signal level measurements must be averaged in order to achieve a sufficient reliability. Averaging causes a delay in measurement results, for which reason such a channel may be allocated the interference level of which has just changed e.g. because another connection has been set up which functions nearby on the same channel. According to the invention, allocation of a channel causing excessive interference with a connection already set up is limited.

IPC: H04M3/53
Filed: 1998-02-26
Abstract: A voice mail system is provided in a CDMA wireless telephone system in which a base station controller (BSC) stores, in a encoded format, voice data transmitted by a wireless telephone to a receiving telephone, either wireless or fixed telephone, when the receiving telephone does not "pick up". Also, the base station controller encodes and then stores voice data that is transmitted by a fixed telephone to a wireless telephone when the wireless telephone does not "pick up". In either case, to retrieve voice mail the intended recipient can access the voice mail from a fixed telephone, in which case the voice mail is decoded at the BSC and then sent to the fixed telephone via a landline. Alternatively, the intended recipient can access the voice mail from a wireless telephone in the system, in which case the voice mail is not decoded at the BSC, but is transmitted directly to the wireless telephone, where the message is decoded. In any case, the voice mail undergoes only a single encoding/decoding process, thereby improving the sound quality of the retrieved voice mail messages compared to systems in which tandem vocoding occurs.
